The AirTAC GFR600C20AF3TK AirTAC Filter Regulator 3/4 in NPT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C20AF3TK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This size 600 unit is built with 3/4 in NPT ports, an automatic drain that clears collected condensate without anyone opening the bowl, a 40 um filter element, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). The embedded square gauge reads in bar, a reverse/check valve is fitted, and the aluminium alloy bowl comes with a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and catalogue options include manual or differential-pressure drains, a finer 5 um element (code W), gauge scales in MPa, psi or bar, and G or NPT threads ordered in place of the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Positioned ahead of the spray-booth drop lines, this unit strips water and particulate from the shop air and holds a steady regulated pressure to the paint guns, helping finish consistency across a shift.
Mounted at the drop from the main header on a cartoning or palletizing conveyor, it cleans the air feeding the pusher and clamp cylinders and keeps their operating pressure stable through the cycle.
On a skid of pneumatic quarter-turn actuators opening and closing process valves, this unit filters the supply air and regulates it to the pressure the actuator and positioner are set up for.
Start with the port step: size 600 carries 3/4 in ports, and the GFR range steps from size 200 up to 600 with ports from 1/8 to 1 in, so match the size to the air demand of your line. Choose the drain: automatic (this unit) suits unattended points, manual suits stations that are regularly serviced, and differential-pressure is the catalogue default. Pick the element: 40 um standard, or 5 um (code W) where finer protection is needed. Gauge scale is selectable - MPa, psi or bar - and this unit carries the square gauge reading in bar. Thread here is NPT; PT is the standard and G (BSPP) is also an order option. Flow is published as curves, not a single rating, so send us your demand and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your line demand and port arrangement and we will confirm the sizing from the datasheet on request.
The A in this model code specifies the automatic drain, which removes collected condensate without anyone opening the bowl - useful at unattended points. Manual and differential-pressure drains are catalogue options across the GFR family if your station is serviced regularly.
